Geoscience BC Releases Two Reports: Linking Geology to Geophysics and Use of Organic Media to "Uncover" Mineralization

December 20, 2013 -Geoscience BC is pleased to announce the release of the following two reports:

Report 2013-14: Linking Porphyry Deposit Geology to Geophysics via Physical Properties: Adding Value to Geoscience BC Geophysical Data
Report 2013-20: Use of Organic Media in the Geochemical Detection of Blind Porphyry Copper-Gold Mineralization in the Woodjam Property Area, South-Central BC (NTS 093A/03, /06)

Both reports are now available for download through Geoscience BC's website at www.geosciencebc.com/s/DataReleases.asp.

Brief descriptions of each report are provided below.

Geoscience BC Report 2013-14: Linking Porphyry Deposit Geology to Geophysics via Physical Properties: Adding Value to Geoscience BC Geophysical Data

This report presents physical rock property data from six BC porphyry deposits (Mount Milligan, Endako, Huckleberry, Bell, Granisle and Morrison) and discusses observed trends within the detailed QUEST and QUEST-West geophysical datasets and mapped geology. The resulting physical rock property data compilation has implications for improving interpretations of geophysical data from porphyry deposits. A synopsis of physical property criteria defining hydrothermally altered or mineralized rocks in BC porphyry settings is provided, which can ultimately be used for ranking similar mineral exploration targets throughout BC, thereby minimizing exploration risk.

Geoscience BC Report 2013-20: Use of Organic Media in the Geochemical Detection of Blind Porphyry Copper-Gold Mineralization in the Woodjam Property Area, South-Central BC (NTS 093A/03, /06)

Plant exudates can contain metals that have been transported from underlying mineralization. These materials include saps, transpired fluids, salts and particulates on leaf surfaces and may offer simple and cost-effective sample media for detecting mineralization under cover.

Geoscience BC Report 2013-20 describes a "proof of concept" study carried out at the Woodjam project in central BC that tested the geochemical response of exudates and spruce tissues collected over the "blind", or covered Deerhorn and Three Firs porphyry Cu-Au systems. Both systems are concealed beneath glacial cover and/or basalt. HR-ICP-MS (High Resolution ICP-MS) was required to obtain low detection limits for some ore and pathfinder elements in the exudates. Results are compared with data from Ah horizon and soil charcoal samples.
